Hi, I'm new here

If I've made any mistake with this question please let me know and pardon me with time to edit it. Thanks.

My Destination:

I'm trying to re-install my Ubuntu 18.04 64-bit in my dell Inspiron 13 5000series i7.
I currently have two operating systems Win10 and Ubuntu 18.04 as dual-boot.

I've already backed up everything, but if I can reinstall without losing my entire disk and my win10 and it's files - I would be very thankful.

My Approach So Far:

These are the steps I took before I got here. Using a live installation:

The reinstall by erasing - I've read it might delete the whole system - I've not taken this road.

So I chose "Something else" -- In the picture my partitioning.

Here is the only thing I've changed - the mounting

And lastly the warning -- This is why I'm posting this question

Why I'm worried:
Someone has raised a question about this but was not given an actual answer:
https://github.com/mate-desktop/mate-desktop/issues/278

This is the bug I'm worried about:
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/556373

From what I've understood it might remove the whole disk, not only
my linux system and files but also my win10..

Because I've half read half guessed it might stems from the home and root being connected
I've checked mine using the df -h and guess what:
They are

Before going on:

 Is it really the source of the problem? or

is there something else I should do? maybe going on won't case any harm to my win10?

So now I'm trying to separate between them - I don't know where I'm going with this.

I'v been following this tutorial to separate my home from my root:
https://www.howtogeek.com/116742/how-to-create-a-separate-home-partition-after-installing-ubuntu/

This is where I got stuck because upon creating the NEW partition to
be the /home the label (or path) is ambiguous "New Partition #1" and I can't find how to put it in a path:
Unclear Path

I'm afraid to do the changes because if the path is ambiguous how could I carry on with reaching this home
partition which is nowhere to be found path-wise.

In summery:

1). If you plan on using already created file systems, be aware...

How do we deal with this kind of warning upon reinstalling - without losing data, or at least not losing any other operating system (like win10).

2). If actually by separating home from root (which is only a guess on my part) how to create a path (or label) in the gparted new partition?

Thanks in advanced.

In my opinion you need not to separate /home and / partitions if you don't really need. Rest is all your wish. You can read Ish's answer.

The warning states that:

No partition table changes and no creation of filesystems have been planned.
If you plan on using already created file systems, be aware that existing files may prevent the successful installation of the base system.

Actually, Linux(let's say Ubuntu here) works on extended file system which is quite obvious that it is a standard. You previously had Ubuntu installed in that partition(lets say sdax). Since you already have that partition with ext4 filesystem and you are just continuing without any changes or creation of File System. It expects that you might have partition in another file system and expects you to change or create a new file system.

Like I already said that Ubuntu works on ext file system and it might expect you to change filesystem or at least format your partition(you haven't checked on Format this partition box). That's why be aware that existing files may prevent the successful installation of the base system.

So, just choose Format this partition and install Ubuntu as usual.
